Description

Technical Field

[0001] This utility model relates to a pulper, specifically a high-concentration paper pulper, belonging to the field of papermaking equipment technology. Background Technology

[0002] A pulping unit is a device used to process waste paper, wood or other cellulose raw materials into pulp. Its main function is to separate the cellulose from the raw materials and to perform steps such as pulping, filtering and discharge in the process. The design and process of the pulping unit can be adjusted according to production requirements and raw material characteristics to ensure that the final pulp produced meets specific quality and application requirements.

[0003] The patent with publication number CN223176481U discloses a paper pulping device. By starting a motor, the rotating rod and the rotating block can be driven to rotate. The stirring rod and the control rod simultaneously make circular motions. The stirring rod stirs the pulp. During the rotation of the control rod, through bevel gear B, bevel gear A, sprocket and chain, it can drive multiple sets of stirring rods to rotate on their own, thereby generating more complex forces on the pulp, further improving the stirring and crushing effect of the pulp and improving work efficiency.

[0004] The above-mentioned patented solution can generate more complex forces on the pulp, further improving the mixing and crushing effect of the pulp. However, the process requires more and more complex structures, and large pieces of raw materials are prone to sinking to the bottom and being difficult to crush, resulting in uneven crushed pulp. Furthermore, it is difficult to clean the mixing rod and pulping tank after long-term use.

[0005] Therefore, a high-concentration paper pulping machine is proposed here. Utility Model Content

[0006] This invention proposes a high-concentration paper pulper that can crush the raw materials settled at the bottom of the pulping tank, thereby improving the crushing efficiency and quality. It can also clean the inside of the pulping tank, the second stirring rod, and the spiral blades after long-term use.

[0007] This utility model is achieved through the following technical solution: a high-concentration paper pulper, including a box cover installed on the upper surface of the pulping tank, and a stirring assembly and a disassembly assembly on the pulping tank and the box cover.

[0008] The stirring assembly includes a toothed ring mounted on the bottom surface of the tank cover. A turntable is rotatably connected to the bottom surface of the toothed ring. Multiple first stirring rods are rotatably connected to the inner wall of the holes on the turntable. A gear is fixed to the top of each first stirring rod, and the gear meshes with the toothed ring. Multiple second stirring rods are fixed to the outer surface of the bottom of the turntable.

[0009] It also includes a rotary motor installed on the upper surface of the box cover. The output shaft of the rotary motor passes through the box cover and is fixed with a rotating rod. The outer surface of the rotating rod is rotatably connected to the inner wall of the hole on the turntable. The outer surface of the rotating rod located below the turntable is equipped with helical blades.

[0010] Furthermore, the bottom surface of the toothed ring is provided with an annular groove, and an annular plate is fixed on the upper surface of the turntable. The annular plate is rotatably connected to the inner wall of the annular groove, which can guide and limit the rotation of the turntable.

[0011] Furthermore, the bottom surface of the box cover is fixed with multiple insert rods, and the upper surface of the pulping bucket is provided with multiple insertion holes, with the insert rods inserted into the insertion holes, which can limit and assist the position of the box cover.

[0012] Furthermore, the disassembly and assembly assembly includes a mounting block hinged to the lid, the mounting block having a slot, and multiple fixing rods fixed to the outer surface of the pulping tank. A locking block is rotatably connected to the end of each fixing rod away from the pulping tank, and the locking block is inserted into the slot. By rotating the locking block to make it coincide with the slot on the mounting block, and then rotating the mounting block outward to make the slot pass through the locking block, the restriction on the lid can be released, thereby allowing the lid to be disassembled from the pulping tank for cleaning of the second stirring rod, the spiral blade, and the inside of the pulping tank.

[0013] Furthermore, a feed pipe is installed on the upper outer surface of the pulping tank, and the feed pipe is located below the turntable, which can put raw materials and water into the pulping tank. A discharge pipe is installed at the bottom of the pulping tank, and a control valve is installed on the discharge pipe, which can discharge the pulverized pulp.

[0014] Furthermore, a handle is fixed to the upper surface of the box lid, which can be lifted. An observation window is provided on the outer surface of the pulping bucket, which can be used to check the pulping status inside the pulping bucket.

[0015] This utility model provides a high-concentration paper pulping machine, which has the following beneficial effects: 1. This high-concentration paper pulper uses a rotating motor to drive a rotating rod, which in turn drives a turntable. The turntable, in turn, drives a first and second stirring rod in a circular motion to mix and pulverize the raw materials. Simultaneously, through the meshing of gears and a gear ring, the first stirring rod rotates while the gears rotate, subjecting the pulp to more complex forces. This improves the efficiency of mixing and pulverizing while reducing the required structure. Furthermore, the rotation of the rotating rod synchronously drives the spiral blades, which in turn move the raw materials settled at the bottom of the pulping tank from bottom to top. These materials are then pulverized by the second stirring rod, thus improving the efficiency and quality of raw material pulverization.

[0016] 2. This high-concentration paper pulper allows the lid to be removed by rotating the locking block to align it with the slot on the mounting block, and then rotating the mounting block outward to allow the slot to pass through the locking block. This releases the lid from the pulping tank, allowing for the cleaning of the second stirring rod, spiral blades, and the inside of the pulping tank. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0020] Please see Figures 1-5 The present invention proposes the following implementation scheme: a high-concentration paper pulping machine, including a box cover 103 installed on the upper surface of the pulping tank 1, a stirring assembly 2 and a disassembly assembly 3 on the pulping tank 1 and the box cover 103.

[0021] The pulping tank 1 has a feed pipe 102 installed on its upper outer surface, and the feed pipe 102 is located below the turntable 203, which can put raw materials and water into the pulping tank 1. The bottom of the pulping tank 1 has a discharge pipe 101 installed, and a control valve is installed on the discharge pipe 101, which can discharge the crushed pulp.

[0022] A handle 1031 is fixed on the upper surface of the box cover 103, which can be lifted. An observation window 104 is provided on the outer surface of the pulping tank 1, which can be used to check the pulping condition inside the pulping tank 1.

[0023] Please refer to this carefully. Figure 2 and Figure 3 The stirring assembly 2 includes a toothed ring 202 mounted on the bottom surface of the cover 103. A turntable 203 is rotatably connected to the bottom surface of the toothed ring 202. Multiple first stirring rods 207 are rotatably connected to the inner wall of the hole on the turntable 203. A gear 206 is fixed to the top of the first stirring rod 207 and meshes with the toothed ring 202. Multiple second stirring rods 208 are fixed to the outer surface of the first stirring rod 207 at the bottom of the turntable 203.

[0024] It also includes a rotary motor 201 installed on the upper surface of the cover 103. The output shaft end of the rotary motor 201 passes through the cover 103 and is fixed with a rotating rod 204. The outer surface of the rotating rod 204 is rotatably connected to the inner wall of the hole on the turntable 203. The outer surface of the rotating rod 204 located below the turntable 203 is equipped with a spiral blade 205.

[0025] Please refer to this carefully. Figure 5 The bottom surface of the toothed ring 202 is provided with an annular groove 2021, and the upper surface of the turntable 203 is fixed with an annular plate 2031. The annular plate 2031 is rotatably connected to the inner wall of the annular groove 2021, which can guide and limit the rotation of the turntable 203.

[0026] Multiple insert rods 1032 are fixed on the bottom surface of the box cover 103, and multiple insertion holes 105 are opened on the upper surface of the pulp bucket 1. The insert rods 1032 are inserted into the insertion holes 105, which can limit and assist the position of the box cover 103.

[0027] Please refer to this carefully. Figure 4 The assembly 3 includes a mounting block 301 hinged to the cover 103, a slot 304 on the mounting block 301, and multiple fixing rods 302 fixed to the outer surface of the pulping tank 1. The end of the fixing rod 302 away from the pulping tank 1 is rotatably connected to a locking block 303, and the locking block 303 is inserted into the slot 304, and the slot 304 is larger than the locking block 303.

[0028] By rotating the locking block 303 to align it with the slot 304 on the mounting block 301, and then rotating the mounting block 301 outward to allow the slot 304 to pass through the locking block 303, the restriction on the box cover 103 can be released, thereby allowing the box cover 103 to be removed from the pulping tank 1, and the second stirring rod 208, the spiral blade 205, and the interior of the pulping tank 1 to be cleaned.

[0029] In use, the raw materials and water are fed into the pulping tank 1 through the feed pipe 102. Then, the rotary motor 201 is started to drive the rotating rod 204 to rotate. The rotating rod 204 drives the turntable 203 to rotate, and the turntable 203 drives the first stirring rod 207 and the second stirring rod 208 to rotate in a circular motion, thus stirring and crushing the raw materials. At the same time, the gear 206 meshes with the gear ring 202, so that the first stirring rod 207 rotates in a circular motion while the gear 206 drives it to rotate, thereby subjecting the pulp to more complex forces and improving the efficiency of stirring and crushing. Furthermore, the rotation of the rotating rod 204 can simultaneously drive the spiral blade 205 to rotate. The rotation of the spiral blade 205 can drive the raw materials at the bottom of the pulping tank 1 to move from bottom to top, and then crush them by the second stirring rod 208, thereby improving the efficiency and quality of raw material crushing.

[0030] When the second stirring rod 208, spiral blade 205, and the inside of the pulping tank 1 need to be cleaned after prolonged use, the locking block 303 is rotated to align with the locking groove 304 on the mounting block 301. Then, the mounting block 301 is rotated outward to allow the locking groove 304 to pass through the locking block 303, thereby releasing the restriction on the tank cover 103. This allows the tank cover 103 to be removed from the pulping tank 1 for cleaning of the second stirring rod 208, spiral blade 205, and the inside of the pulping tank 1. Conversely, it can be installed.
